About

From bootstrapping in Romania to building fintech infrastructure in London.

The Journey

Started bootstrapping early in Romania (City365), building high-scale Azure backends for hyper-local deals.

Moved to London to lead mobile/frontend eng at fast-paced startups like Zebra Fuel (logistics) and Stint (workforce), managing teams of 6+.

Co-founded Yayzy to solve a harder data problem. Learned how to raise ($1.5M), hire/manage (team of 7), and ship bank-grade secure infra under pressure—featured by Apple, Forbes, and TechCrunch along the way.

Now focused on fintech infrastructure and AI product engineering—building systems that are secure, scalable, and actually ship.

How I Work

Ship, then iterate

Perfect is the enemy of shipped

Own the outcome

Not just the code

Security by default

Not as an afterthought

Clear > clever

Maintainability wins

Outside Work

I clear my head with morning runs around London.
